Physical properties
Hardness of 3.5 to 4 on the Mohs scale, color ranges from dark grey to black, submetallic to metallic luster, amorphous crystal structure with no cleavage, specific gravity of 1.9 to 2.1.
Formation & geological history
Formed in ancient organic-rich sedimentary deposits through low-grade metamorphism over 2 billion years ago, primarily found in Karelia, Russia.
Uses & applications
Used in water filtration, jewelry, EMF protection items, and as a decorative stone.
Geological facts
Shungite is notable for containing fullerenes, a unique form of carbon molecules, and is found in commercial quantities almost exclusively in the Zazhoginsky deposit in Russia.
Field identification & locations
Identified by its deep black color, soft to medium hardness, and lightweight feel due to low specific gravity. Highly conductive due to its carbon structure.
